d. Any depth

Alpha-beta pruning can be applied at any depth in a game tree. It is not limited to a specific number of states. The purpose of alpha-beta pruning is to reduce the number of nodes that are evaluated by the minimax algorithm in a search tree. It stops completely evaluating a move when at least one possibility has been found that proves the move to be worse than a previously examined move. Such moves need not be evaluated further. When applied to a standard minimax tree, it returns the same move as minimax would, but prunes away branches that cannot possibly influence the final decision.
